Website for Rost et al/Plant Biology 2e, ISBN: 0534495958 Objectives Chapter #13 Chapter 13 The Flower and Sexual Reproduction OBJECTIVES After reading this chapter, you should be able to: ■ List the features that distinguish the angiosperms from other groups of plants. Make a diagram of a typical flower. Name and state the function of each floral part. Explain the changes that take place as the shoot apex is transformed into a floral apex. ■ Describe the complete sexual cycle that takes place in the flower. Outline the steps involved in the formation of the pollen grain (male gametophyte) and the embryo sac (female gametophyte). Define the term “double fertilization” and describe the products of each sperm fusion. ■ Describe the variations in symmetry, ovary position, fusion, pigmentation, etc., that occur in floral architecture. Show how these variations are related to differences in pollination strategies. Explain why these variations are important to understanding the evolutionary relationships among angiosperms. ■ Distinguish between pollination and fertilization; a simple flower and an inflorescence; a complete flower and an incomplete flower; a perfect flower and an imperfect flower; adnate and connate; and an ovule and a seed. ■ Define all boldface terms.
